Most beautiful women have a 6th sense for insincerity, a bullshit sense.
There are literally thousands of potential telltale signs that will warn an intuitive female of your fakeness, some people call these 'micro gestures' and only the greatest actors come close to mastering these telltale signs.
Perhaps the answer to your question is right in front of you, why didn't it work? Because you were using a line. Perhaps the question you should be asking is why did I feel like I needed to use a line?
Why couldn't you just approach this girl with Rockstar confidence and tell her that you want to meet her, that you find her interesting. Then be selectively honest.
I.e.
Blatantly honest.
'Hi, I think your tits are stunnerz and I'm secretly hopin your slutty enough to give me a gobby in the bathroom, because I really need a good no strings attached lay to boost my confidence, how about it?'
Selectively honest.
'Hi, I think you're cute, tell me your name'
You have just met a girl for the first time and you have already based your entire relationship on a lie. What are the chances of it progessing to something positive from here?
Next time you are in that situation don't 'intuitively lie', if lying is something you do intuitively then you have a problem. Next time follow your instincts instead.
What is the difference? Instinct requires no thought process, it is completely honest and true, it is getting in touch with your primal self. The part of you which has been fine tuned through millions of years of evolution, the most basic fundamental quality of every human being and the very root of all sexuality.
This is where you should be operating from, this is what should drive your actions, not the psychological complex you have developed from a history of negative experiences with women.
This is a self perpetuating thought process, otherwise known as a negative feedback loop, this is what I believe you are suffering from now and what is stopping you from reaching your full potential. Lying is negative behaviour and therefore it creates negative outcomes and feeds an unproductive cycle.

If you want to start having positive relationships with women then you need to consciously break this cycle and start being true to yourself and true to women.
Forget what you know about women and their cruelty, stop trying to trick them into liking you. How would you feel if you found out one of your friends was only using you to borrow your Playstation 3/Xbox games?
This is how a woman feels when she thinks a guy is trying to cheat her into liking him.
The only person you are really cheating though is yourself, you are cheating yourself out of real relationships, you are cheating yourself from getting laid, you are cheating yourself into thinking you are unworthy.
I think you are worthy, I think you are an intelligent capable human being and I've never even met you, about time you start thinking the same.
